APPARATUS FOR COOLING AND PRESERVING BEER.

SEGIFICATON formng' part of Letters Patent NO. 667,O4, dated February 5,1901.

Application filed June 17, 1899.

TO all whom ;it may concerns Be it known that I, ALFRED COBLEY, acitizen of the United States, residing at Irvington, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Apparatus for Cooling and Preserving Beer; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The objects of this invention are to increase the pressure inpartly-emptied kegs of beer without at the same time raising itstemperature or permitting the introduction to the beer-cask of noxiousgases or the seeds of disease, such as are commonly found in theinterior oi' a saloon, where a large number of men are congregatedsmoking, expectorating, &0.

The invention consists in the improved means for introducing cold,compressed, invitiated atmospheric air to the keg and in thearrangements and conbinations of parts of the same, all substantially aswill be hereinafter set forth and finally embraced in the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the views, Figure 1 isa sectional View of a portion of a building containing a bar and showingthe relation of the various pipes,valves, the., conprising myimprovements to the said bar and kegs from which the drinks aredispensed. Fig. 2 is a detail side elevation, partly in section, of anair-pump of my improved Construction.

In said d rawings, a indicates the fioor of a building, above which isarranged the bar Z), having the ice-box c, of any ordinary construction.

dindicates the air-pump, by means of which the open air is forced into areservoir e through a pipe f, said reservoir ordinarily being stationedbelow the fioora in the cell-are beneath the saloon. g indicates a pipeleading from said reservoir upward to the bar, where it is provided witha pressure-indicator h, by means of which the barkeeper may see SerialNo. 720,887. (No model.)

the condition of pressure in the cask or kegs at any time.

From the indicator h the pipe ?I returns to the cellar, where it is inconnection with a common pipej, provided with suitable pipe connections,by means of which the fiexible branch pipes or tubes Ic k are connectedto the kegs ZZ. The kegs Z are provided with suitable bung valves orfaucets m, adapted to receive the pipes 75 76 and pipes o, through whichthe beer or other liquid is conveyed upward to the bar, the said pipes oo passing through the ice-box c, where the said pipes are properlycoiled in any ordinary manner to cool the beer passing therethrough,andthe beer is ready to be dispensed to the customers.

Heretofore the air-pump d has opened directly into the saloon and takenth e air thereof, and because of the impurity of such air, due to thepresence of smokers and other vitiating causes, there has been areduction in the purity of the beer, and because of the heat of thesaloon the same has caused an unnecessary heating of the beer,requiringa greater supply of ice to counteract the effect. By myimproved construction I connect to the said pump d a pipe 10, which eX-tends through the ice-box c, where it is turned into a coil q to coolthe air passing therethrough, and thus a supply of cold airis furnished,which is cooled before it passes into the pump and reservoir c. From thecoil q the pipe extends out from the ice-box and opens into theatmospheric air outside of the saloon. The air thus introduced to thebeer is free from contaminating influences above referred to and isinitially cooler than the saloon air and is further cooled by the air orice in the ice-box before being sent into the cellar. When it arrives inthe beer-keg, it is still at a low temperature and tends to keep thebeer fresh and pure, preventing an acetic fermentation of the beer, dueto a high temperature.

The pump dis provided at its lower end not only with a valved nozzle orconnection r for the pipe leading to the reservoir, but is also providedat a point opposite said nozzle or connection with a second nozzle orconnection s, in which is inserted a check-valve t. Said nozzles areeach furnish ed asecond valve u u', operable by means of a handle, bymeans IOO of which should the cheek-valve get out of order theconnection with the outside air and coil v may be eut ofi' and the pumpemployed in the ordinary manner, taking its air from the inside of thesaloon.

Instead of the hand-operated pump d shown for compressing the air itwill be obvious that the eooled air might be forced into the supply-tankor the eask by other means commonly employed, such as by water-pressureor the like. Any suitable method of indueing a flow of air may be used,this feature constituting no part of my invention.

Having thus described the invention, what I claim as new is- Theheroin-described apparatus for cooling beer for a bar-room withoutimpregnating it with inpurities, eombining With a bar, an iceboxarranged beneath said bar, a keg or other supply-reservoir for the beer,abeer-pipe leading from the lower part of said keg or reser- Voirthrough the ice-box and terminating at the bar above said iee-box in afaueet for drawing the bee', an air-pipe leading intd the top of thebeer-keg from a compressionohamber, an air-pump having a dischargepipeleading into said eompression-chanber and an inlet pipe, said inlet-pipeextending from said pump through the ice-box and through the wall of thebar-room, its open extremity thus lying outside the bar-room and takingin air free from the oontaminations of the bar-room, andthat portion ofthe pipe intermediate of its ends which passes through the ice-box beingeoiled to cool the air drawn from outside the bar-room, Whereby coldpure air is pumped into the beer-keg, substantially as set forth.

In testinony that I claim the foregoing I have hereunto set my hand thisth day of June, 1899.

ALFRED COBLEY.
